摘　　要：为了深入研究海拉尔盆地外围凹陷的油气地质条件,加快勘探进程,立足乌尔逊—贝尔凹陷与外围凹陷已有的油气勘探资料和认识,从石油地质特征人手剖析了二者的相似性与差异性.相似性为都经历了3期构造演化,凹陷内具有“分块、分带、分层”的特点,南屯组及以下地层是主要烃源层,储集相带类型、有机质丰度、油气聚集受断裂带控制明显;差异性主要表现在凹陷结构、构造演化、构造带类型、油气性质、烃源岩及其热演化、沉积储层、成藏组合和成藏模式等8个方面.石油地质类比表明,外围凹陷的油气勘探需要利用乌尔逊—贝尔凹陷的勘探成果与经验,结合自身石油地质特征,构建新的勘探思路。In order to deeply research the petroleum geological conditions and accelerate the exploration process for the peripheral sags in Hailer Basin,on the bases of the available exploration data and understandings of WuerxunBeier Sag and peripheral sags,the very similarities and differences between them are analyzed from the viewpoints of the petroleum geological characteristics.Both of them share the following common points：have experienced three stages of the tectonic evolution; characterized by segmentation,zonation and stratification; Nantun Formation and the formations below it are the main hydrocarbon source rocks; types of the reservoir sedimentary facies,organic matter abundance and hydrocarbon enrichment are obviously controlled by the fault belts.Differences are generally shown in the following eight aspects,such as the sag structures,tectonic evolutions,tectonic belt types,oil and gas properties,hydrocarbon source rocks and their thermal evolutions,sedimentary reservoirs,reservoir-forming combinations and hydrocarbon accumulated patterns.The petroleum geology analogy indicates that the oil and gas exploration in the peripheral sag needs taking advantages of the exploration achievements and experience in Wuerxun Beier Sag and combining with the petroleum geological features of themselves and finally establishing the new exploration idea.
